2006-10-18	Want to stop passing x/y/width/height to Clear() function.	Brian Paul
	The coordinates need to be computed after we've got the hw lock. Code updated to: 1. Ignore all/x/y/width/height/ params passed to Clear func. 2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.
2005-10-31	fix problems found with gcc 2.96 (bug 4934)	Brian Paul

2005-09-03	SetBuffer, renderbuffer changes	Brian Paul

2005-05-04	Major check-in of changes for GL_EXT_framebuffer_object extension.	Brian Paul
	Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2005-03-14	When timestamping textures, need to emit the event with SAVAGE_WAIT_3D	Felix Kuehling
	set. Otherwise the 3D engine may still be using a texture that is being overwritten. In order to minimize the cost of waiting, timestamp textures only when needed: when a texture image changes, when a different texture is bound to a texture unit or when a texture unit is disabled. (Used to be after flushing every command buffer.)
2005-03-06	Don't synchronize after each frame. Allow the GPU to be one frame	Felix Kuehling
	ahead of the CPU for more parallelism of CPU and GPU. Unfortunately there seems to be some broken hardware (like my ProSavageDDR) on which status register updates are delayed sometimes. This leads to very jerky animation if the hardware can buffer more than the current frame. A new option "sync_frames" can be used as a remedy on such broken hardware.
2005-03-06	- Fixed two bugs related to DMA buffer handling that showed up with the	Felix Kuehling
	new DRM version 2.4 and command DMA. - Flush less. - Bumped the driver date.
2005-02-23	With Savage DRM version 2.3.x or later use event counters for texture	Felix Kuehling
	heap aging, similar to the way it's done in the i810 and i855 drivers. This avoids idling the engine on every texture upload.
2005-02-12	Make glean's masked clear test pass.	Felix Kuehling

2005-02-05	- Fixed scissor rectangle not moving with the window (Xorg bug #1731).	Felix Kuehling
	- Flush buffered primitives before changing scissors. - Require Savage DRM version 2.1.0, so that the broken single-cliprect code can finally rest in peace. - Removed some more dead code.
2005-02-02	Fixed flushing of client-side vertex buffers.	Felix Kuehling

2005-01-21	Small cleanup:	Felix Kuehling
	* Remove some unused (mostly empty) functions * Added context parameter to WAIT_IDLE_EMPTY[_LOCKED] for consistency * Added debug messages to WAIT_IDLE_EMPTY[_LOCKED] * Don't flush empty command buffers
2005-01-20	Added support for ELTS to the _savage_render_stage. Requires at least	Felix Kuehling
	Savage DRM version 2.2.0. Otherwise the render stage is disabled.
2005-01-03	Added support for floating point depth buffers on Savage4-based	Felix Kuehling
	hardware. By also reversing the depth range this can compensate the loss of accuracy of far objects caused by the projective transformation. Software fallbacks work but are slightly slower since floats in a custom (non IEEE) format have to be encoded and decoded. I havn't done anything about polygon offsets yet. There doesn't seem to be an easy way do get it right except making the offset unit as big as the lowest resolution of depth values. For now float depth is disabled by default but can be enabled through driconf (though I have seen only positive effects so far).
2005-01-01	Removed all direct hardware access (MMIO, BCI) from the Savage DRI	Felix Kuehling
	driver. It uses the new DRM version 2.0.x now, which has just been committed to DRM CVS.
2004-12-14	uintt -> u_intt	Alan Hourihane

2004-10-08	Apply Eric's stencil wrap patch (Eric Anholt)	Alex Deucher

2004-05-24	WAIT_IDLE_EMPTY in savageSwapBuffers until real frame throttling is possible.	Felix Kuehling

2004-05-03	get rid of last few XF86DRIClipRect	Dave Airlie

2004-03-26	Enable drawing directly to the (now tiled) front buffer.	Felix Kuehling

2004-03-24	Make sure hardware culling is disabled for unfilled primitives,	Felix Kuehling
	points and lines.
2004-03-24	Buffer vertices and emit them in batches. Still using conventional drawing	Felix Kuehling
	commands, no vertex DMA.
2004-03-21	unsigned int -> uint32_t, unsigned char -> uint8_t where the size matters.	Felix Kuehling
	A bit more cosmetics. Improved state emit on Savage 3D/IX/MX.
2004-03-20	Fixed MAXFIFO_S4. Removed WAIT_IDLE_EMPTY from savage_BCI_swap which resulted	Felix Kuehling
	in another small speedup. Fixed a problem that was masked by that WAIT_IDLE_EMPTY: - flush command buffer and WAIT_IDLE_EMPTY before uploading textures
2004-03-04	Clearing rectangle was one too big in each direction.	Felix Kuehling

2004-02-29	Reorganized hardware state data structures and state emission. Don't track	Felix Kuehling
	which registers changed in all the functions that change the state. Instead check which registers changed in the end when the hardware state is updated. Tried to avoid cosmetic (whitespace) changes in this commit.
2004-02-22	Imported the Savage DRI driver from the savage-2-0-0-branch of DRI CVS	Felix Kuehling
	with modifications to make it work with current Mesa 6.
